Weight and Rep Calculator

The calculator below will predict the maximum amount of
weight you can use for a specified number of reps if you know how many reps you
can do with a given weight now (your nRM). It also predicts the number of reps
you can perform with another weight. It is based on manipulations of the
Brzycki, Epley and Lander Equations. Keep in mind that these calculations are
not typically accurate for rep counts of higher than 10 to 12. For more
information on what these estimates mean, and how they should be used, please
see the article Formulas And Coefficients That Predict Your 1-Rep Maximum
on the Training Related Articles page.
